So I am planning to download and experiment them in a virtual machine ( to setup a VM windows and install and run WAIK in it. Then build my Custom media for windows 7 sp1 x64 for my particular system.

I think of using the WAIK for later for my other win7 systems ( one or two to achieve their custom mathced installation media and boot time recovery media )

for recovery purpose I have been experimenting with GHOST and ACRONIS times back. but I wish to create a solution like a branded system recovery method. Just press a key at the bios boot time and it deploys a custom made image to bring things to factory installed state.

That's all my understanding and I need advice/suggestion, am I on the right track?

Should I download and go ahead for the two huge WAIK file and start playing ?
